UNITED STATES PATENT OFFICE.

HENRY B. BABBITT, OF PAXlON, INDIANA.

PEA-HULLER.

SPECIFICATION forming part of Letters Patent No. 450,051, dated April '7', 1891.

Application filed June 10, 1890. Serial No. 354,895. (No model.)

of Indiana, have invented certain new and usefullmprovements in Pea-Hullers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide an improved pea-huller to effect the thorough and expeditious separation of the peas from the pods or envelopes; and theinvention consists in the construction and combination of the parts, as will hereinafter appearfrom the following description and accompanying illustration.

In the accompanying drawings, Figure 1 is a front elevation of my improved pea-huller.

Fig. 2 is a side elevation thereof. Fig. 3 is a sectional elevation of the same, and Fig. 4 is a transverse section of the screen-cylinder.

In carrying out my invention I employ a suitable frame A, the ends of which are pref- 2 5 erably boarded up.

B is a screening-cylinder driven by a belt and pulley-head a and loosely journaled or hung upon a shaft 0, itself journaled in endpieces of the frame A and having a driving- 0 belt pulley on one end for its rotation.

The cylinder or screen B has secured to one end upon the inner side the conical feeder or ring I), and for convenience of access to the interior of said cylinder it is pro vided with a cir- ,cumferential door-section b, suitably hinged in position and held in place by hasps 12 in turn hinged to the peripheries of the heads of said cylinder and engaging staples b projeoting from said peripheries, and hooks b also connected to the latter and engaging said staples.

Directly above the screen or cylinder B is a hopper 0, into which the peas are first placed and fed through a series of peripheral open- 5 ings b in the head end of the cylinder.

Upon the shaft 0 are arranged radial feathered blades or paddles D D, adapted to beat and break the pea-pods, and thus shell or hull the same and move the shellsor hulls toward the discharge end of the cylinder, while the liberated peas drop through theinterstices or apertures of the screen or cylinder, the shells or hulls dropping through the openings b at the discharge end of said cylinder.

E is an endless apron arranged immediately below the cylinder or screen B and encompassing two bearers or shafts d d, so as to engage and revolve the upper one d, the lower one d being driven by a belt-pulley upon its projecting end, in turn driving the apron. The plane of movement of the apron is at right angles to that of the movement and lon-' gitudinal axis of the cylinder or screen B, so that it will receive the peas dropping from the latter and discharge or deliver them on the floor or into a suitably-placed receptacle at one side of the separator. Any peas that may escape at the forward end of the cylinder or screen B will be received into the spout e, secured thereunder, and in an opening in that end of the frame or support A, and be discharged thereat.

F is a riddle suitably mounted upon a supplemental frame or annex A of the frame A, its inner end being arranged under thedelivcry or discharge end of the cylinder or screen B and its opposite end projecting some distance from that end of said frame or annex and discharging upon the floor or into a receptacle suitably disposed.

The riddle F is guided in its laterally-vibratory motion by pendants f f thereof, projecting into a space left between the main frame A and the supplemental cross-pieces of said frame A and receiving its motion by -means of a pitman g, eccentrieally connected to the shaft d and preferably engaging said riddle by means of a hook and eye or staple. Thus the upper shaft or bearer of the'apron E also reciprocates the pitman 9.

Any peas falling from the riddle with the hulls or shells can again be passed through the separator for further treatment to effect their separation.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-

1. The pea=-separator having the screeningcylinder provided with series of peripheral feeding-openings at its head end and a similar series of openings at its discharge end, the feed-hopper, the internalconical ringor feeder,

openings at its delivery end,of the feed-hopper and the shaft carryingthe radial feathered blades or paddles Within said cylinder, said cylinder revolving upon and independentof said shaft and said shaft having a rotary motion of its own, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
